Sporting director Walter Sabatini is hopeful Mirko Vucinic will remain at Roma next season.
The Montenegrin forward is in pre-season training with Roma but has said he wants to leave the Serie A side after having a strained relationship with the club's supporters last term.
The 27-year-old has been strongly linked with a move to Juventus in recent months, while Blackburn have also been mentioned as possible suitors.
But Sabatini is optimistic Vucinic can put last season's problems behind him and believes his best days with the Giallorossi could be yet to come.
"Mirko has endured a negative atmosphere," he said. "But I consider him a great player who has room for improvement.
"He could become an even more important player for Roma and I would like him to remain.
"We will see how he experiences the first few days of training and what his relationship will be with the staff.
"If he should leave, he will not be included in an exchange deal or sold cheaply.
"He is one of the few players in Italy that can determine the result of a game on his own."
Vucinic scored 10 goals in 28 appearances last season to help Roma finish sixth in Serie A.
He is under contract with the Giallorossi until June 2013 after joining the club from Lecce in 2006.
